    摘要： To provide a blood purification apparatus in which whether or not the connection of a communicating line is appropriate can be determined more accurately. A blood purification apparatus includes a control device 16 that is capable of executing a pressure-applying step in which a negative pressure or a positive pressure is applied to a flow route of one of a tube section and a blood circuit; a propagating step in which the negative pressure or the positive pressure applied in the pressure-applying step is propagated to the flow route of an other of the tube section and the blood circuit through the communicating line; and a checking step in which whether or not the propagation of the negative pressure or the positive pressure in the propagating step is successful is checked with reference to the pressure detected by the pressure-detecting device, and in which whether or not the connection of the communicating line is appropriate is checked with reference to whether or not the propagation of the negative pressure or the positive pressure is successful.

    摘要： The invention relates to a device for the pressure-based detection of a clot in an extracorporeal blood circuit. The device comprises at least one cyclically operating pump for pumping the liquid located in the extracorporeal circuit and at least one pressure sensor, which is arranged so as to ascertain the current pressure curve over time in the liquid pumped by the pump in a current pump cycle, wherein the device has at least one storage device in which at least one reference pressure curve is stored based on at least one pressure curve over time that has been ascertained in a pump cycle of the pump preceding the current pump cycle of the pump, and the device comprises at least one analysis unit which is designed to compare the current pressure curve with the reference pressure curve in a time-corresponding manner.

    摘要： A device is configured to monitor the integrity of a connection system between first and second fluid containing systems comprising first and second pulse generators. A pressure sensor is arranged in the first fluid containing system to detect first pulses originating from the first pulse generator and second pulses originating from the second pulse generator. The device operates a monitoring method, by generating (42) a time-dependent pressure signal based on measurement data obtained from the pressure sensor such that the pressure signal contains a sequence of apparent pulses. The apparent pulses represent a superposition of the second pulses on the first pulses when the connection system (C) is intact. The device processes (44) the pressure signal to calculate a parameter value based on a pulse feature of at least one of the apparent pulses in the pressure signal. The parameter value represents a disturbance caused by the superposition of the second pulses on the first pulses, and may be given as a measure of statistical dispersion, pulse-to-pulse symmetry, or first pulse similarity. The device determines (45) the integrity of the connection system based at least partly on the parameter value. The first fluid containing system may be an extracorporeal blood circuit, and the second fluid containing system may be a human or animal subject.

    摘要： In an extracorporeal blood treatment apparatus, a user interface (22) has a touch screen for displaying two bar-graphs (24) of pressures in the extracorporeal blood circuit. By touching a bar-graph three alpha-numeric values appear: a reference value (29), an upper safety interval (28) of the pressure, comprised between an upper limit value and the reference valve (29), and a lower interval value (30), comprised between the reference value and a lower limit value. The reference value is a measured pressure value. Four buttons also appear on the display for input of modifications to the upper interval and the lower interval. The setting of the total pressure safety interval is simple and immediate.
